Does anyone know why there are 2 67 headlight switches. Std.1995147 and 1995149 w/U17. Does the 149 have a higher rated light dimmer for the console ? See VPC 12 B6 and revision 4. Huh

Ralley Sport headlight door control would be my guess.

The November, 1968 parts book shows one switch for all '67 Camaro applications (#1995164, which superceded #1995149).

JohnZ,
The 68 AIM 12 B6, revision 1, Dated 6-29-67, verifies what you said is correct. My 69 parts book also gives the 164 as the correct number.
Was the RS option available at the start of production on the 67?
Tom,
Looking at the std. and RS wiring diagrams, shows no need for a different switch (all wiring is the same at the switch).
Maybe someone with a 67 parts book could see if there are 2 part numbers used in 67 for the headlight switch.
Does anyone have a picture of a 1995149 headlight switch?

Merry Christmas to all.

Don't have a 67, or an RS. As I stated, just a guess. This time a wrong guess. It's great to have folks like John on this site.
Merry Christmas

Maybe someone can help me look it up. I have a 65-75 Chevrolet parts catalog and I'm looking in group 2.485 which is switches - lighting. I can't find any of these numbers.. Am I looking in the right place?
I just got the manual on pdf. It's huge and I don't know how to use it yet.

For example, it lists three 69 Camaro swtches though..
w/o RS, w/o console inst. cluster (U17) 1995175
w/RS, w/o console inst. cluster 1995176
w/o RS, w/console inst. cluster 1995177
w/RS, w/console inst. cluster combination not shown but w/o RS, w/console inst. cluster is listed twice. However, below this combo is 1995177 but U17 makes no mention of a different switch.

The 69 AIM lists 1995175 as non RS UPC12-B2
RS as 1995176 and RS w/U17 1995177. RPO Z22-B7. Same deal. A different switch for U17, but only with RS.
All this time, I also thought there was just two.

Confused? Me too.. Tongue

Just to add a little more confusion the 69 Camaro Master Parts Manual from 1972 lists four switches for 69 Camaros.

1995173 - All exc RS - with console gauges
1995175 - All exc RS - exc console guages
1995176 - All with RS - exc console guages
1995177 - All with RS - with console guages

1995179 - 167 All, 1968 all exc RS, sup 1995164
1995167 - All with RS - type #D1574

The theory has always been that the dimmer on the RS switches had a higher power rating on it to account for the extra bulbs in the console guage housing.  I think I saw a picture of the two of them side by side and there was a size difference in the dimmer resistor but I don't have the picture on my PC.

You are looking in the correct group (2.485). The reason you can not find the service numbers I quoted is that they have been superseded in later parts books. That is the reason to try and use parts books that are printed for the model year in question.
A picture of the  67 (1995149 w/ U17) headlight switch would be greatly appreciated
Does anyone have a 67 parts book that would look up the two part numbers in question (1995147 & 1995149) and let us know what you find?

The 1995147 and 1995149 are production part numbers, not service part numbers.  There are two different numbering systems used by GM.  The engineering, or production part numbers are those parts made either by GM or by a subcontractor (like Delco) in accordance with design documents and installed on the vehicle in the assembly plant.  Service part numbers are for parts that may be exactly the same as the production part, or they may be a functionally acceptable part that will fit and function the same as the original but it may not look exactly the same.  The Service parts department can either keep the same part number or can assign new number if the original part number does not fit into their numbering system.  Initially the service department may carry both of these switches , or maybe they carried the RS switch but substituted one from a 66 or 67 Chevrolet for the other part since it was deemed to be funtionally identical.  A few years later they may consolidate those two switch part numbers down to just one, and a few years later just stop carrying the part all together.

Can someone with an original 67 w/gauges, be so kind, as to look at the bottom of the light switch and let us know the 3 numbers stamped in the metal cover?

Pretty interesting!  Does the '67 AIM call out a headlight switch in the U17 UPC?  The '68 Z22 does...

It calls for an 1995149 w/U17 gauges. The standard w/o gauges is 1995147. I believe that the 149 has a higher capacity dimmer sw. and if people are adding center consoles w/ gauges and do not upgrade their sw. there could be serious overheating problems.
I have not had a responce that might help answer the matter.

Again, very interesting!  I guess if that is the case (higher capacity), the '68 was already that way.  So, no change for U17.  Changes along the way still happen even these days.  Just look at the electronic industry!  Good luck to you.  It's a tough road trying to figure this one out.

Chris,
JohnZ only indicated that the 149 sw. was changed to the 164 sw. in 68. He did not comment on what switches may have been used in 68, so 68 could also be a problem.
Also note Mark's responce that in 69  173 w/ gauges and 175 w/o gauges.
Mark,
My 67 sw. has the last three digits (147) of the part number stamped on the metal bottom, so I believe that the production number and the service number are the same in this case.
